Get the group info for a group that has been previously queried. The shared pointer will be empty if the group has not been successfully queried (or if it was purged from the cache). From time to time, the cache may be cleaned up. Keep a shared pointer to groups you care about or be willing to re-query.
Shared pointer to the cached group info structure if one exists.
